During the past few years, a significant number of international events (cyber-attacks against Estonia, infiltrations against European and American military networks) had put cyberspace under the limelight of the strategic stage. It is thus possible to envision cyberspace as an autonomous social world where States and non-State actors compete. At the same time; in spite of a proliferating number of works about the IT revolution and its consequences for modern armed forces, many pitfalls remain, including attack attribution, its actors’ intention and institutionalization of means dedicated to cyber-defense in the United States and in France. This bureaucratic issue has a core doctrine dimension : if cyberspace is an autonomous space, can classical dispute frameworks such as deterrence be applied? As political and military decision-makers have not yet delivered conclusions on the matter, it is then important to structure a research agenda that may support these works.
